Ice Age: The Meltdown, is seen through the eyes of Scrat, the saber-toothed squirrel. Scrat is making
his way to finding more and more acorns and assorted nuts as he, like
all of the megafauna of the Ice Age, makes it to safety from the
oncoming flood. As he makes it through, he must find nuts by solving
puzzles, helping out other animals in their pursuits, and generically risking his life by occasionally fighting some rogue animals which wish to do him harm. As he moves
along, he usually has a run-in or two with Manny, Sid, Diego, the
Possum brothers, Ellie, Cholly, or some other animals which help him
out in his pursuits.
